WINDOW.

SPECIFICATION forming part of Letters Patent No. 520,327, dated May 22,1894.

Application filed January 5, 1894. SeIialNo, 495,824. (No model.) l

To aZZ whom it may concern:

Be it known that I, RUDOLPH J. MITCHELL, of Jenkintown, in the county ofMontgomery and State of Pennsylvania, have invented a new and ImprovedWindow, of which the following is a full, clear, and exact description.

My invention relates to improvements in window construction; and theobject of my invention is to produce a window in which the sashes slidevertically in the ordinary way, and which is also arranged in such amanner that the sashes may be swung inward so as to throw open the wholecasement and bring the sashes into position where they may beconveniently repaired or the glass washed or removed.

A further object of my invention is to arrange the details andaccessories of my improved window construction, in such a manner thatthe improvements may be applied to an ordinary window in an oldbuilding, as well as to new constructions.

To these ends, my invention consists of certain features of constructionand combinations of parts, which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views. v

Figure 1 is a perspective view of a window, showing theimprovedconstruction, the lower sash being shown as swung inward. Fig. 2 is avertical section on the line 2-2 of Fig. 1. Fig. 3 is a broken detailfront elevation, illustrating the arrangement of the button which holdsthe lower sash at the right height to be opened. Fig. iis a verticalsection on the line 4.-4 of Fig. 2. Fig. 5 is a sectional plan view onthe line 5--5 of Fig. 4. Fig. 6 is a detail sectional plan of one of thelower sash hinges. Fig. 7 is a sectional plan view showing thearrangement of the upper hinge of the upper sash. Fig. 8 is a detailperspective view of one of the sash latches which also engages the sashcord. Fig. 9 is a detail sectional plan of the lower hinge of the uppersash; and Fig. 10 is a detail perspective view of the lower hinge pintleon the upper sash.

The window frame 10 may be of any usual kind and in it are held thesliding sashes 11 and 12, which also may be of any approvedconstruction, except for certain details to be usual way, but the lowersections 14 and 15 respectively of said parts are hinged, as shownclearly in Fig. 2, so that they may swing inward and thus make way forthe swinging of the sashes, as hereinafter described. If desired, thehinges of the section 15. maybe of such construction as to permit thesection to be lifted oif the hinges and thus removed.

The sashes are provided with the usual sash cords 16, and with thecustomary grooves 18 and mortises 18 to-receive the cords. The cords 16run over the usual pulleys 17 and are provided with the customary sashweights, and one cord of each is attached to the hinged edge of the sashin the customary manner, while the other cord is attached to the latchof the sash, as described below.

The hinges of the lower sash each comprise an eye 19 which is secured tothe window frame, adjacent to the sash stile, the eye being open on itsinner side, as shown clearly in Fig. 6, and a hook which is secured tothe sash stile and comprises a plate 20, bent outward at one edge andmerging in a rod 21, which is adapted to slide through the eye, theplate 20 being slotted, so that when the sash swings open, as in Fig. 1,the eye 19 mayswing through the slot of the plate. The rod 21 is ofgreater diameter than the width of the opening in the eye 19, while thesaid opening is of greater diameter than the thickness of the plate 20,hence the sash may be raised vertically when it is in its normalposition, as the bent end of the plate 20 slides through the opening inthe eye, but the sash cannot be accidentally removed from its hinges.

When the sash 12 is swung open, the eyes 19 enter the slots of theplates 20 and effectually prevent the sash from being removed from itshinges. The swinging or free edge of each sash 11 and 12 is providedwith a latch to which the sash cord 16 is secured, which latch is heldnormally in the sash but may be detached so as'to permit the swinging ofthe latter. The latch has a tube 22 at its inner end, in which the sashcord is held, and a laterally-extending arm 23 on the tube, whicharmterminates at its outer end in a thumb piece 24 to facilitate itseasy turning. The latch lies normally in a mortise 25 made transverselyin the stile of the sash, and it is provided with an extension 26 which,when the latch is swung outward, is adapted to hold the sashsufficiently to prevent it from being raised, and this extension or toe26 is adapted to swing around the inner portion of the mortise wall, asshown in Fig. 5, so as to prevent the too easy displacement of thelatch. On the under side of the arm 23 of the latch is a spring 27,which is secured at one end, and its opposite end 28 is bent upwardthrough a hole in the latch, see Fig. 8, and this end bears against theupper wall of the groove or mortise 25 sufliciently to hold the latch inplace in the sash, and it is also adapted to press against the wall ofthe groove 29 in the frame 10, see Fig. 5, sufficiently to hold thelatch open when it is swung outward into the said groove. To open thelatch and also the sash, it is of course necessary to have the arm 23 ofthe latch register with the groove 29, and to enable this to beaccurately and quickly done, a button 31 is arranged on the lower bead32 of the Window frame, which button may be turned beneath the sash 12,and thus, by raising the sash and then turning in the button, the sashwill be stopped when it strikes the button, and the height of the buttonis such that the arm 23 of the latch will, at this time, register withthe groove 29, so that the latch may be easily opened. The groove 29,besides serving to receive the arm 23 of the latch, receives also acatch 30 on the section 15 of the bead 15, so that when the said sectionis closed the catch will keep it so.

The upper sash is adapted to swing inward like the lower sash, thesection 14 of the parting strip being first opened, and to bring thelatch of the upper sash at the right height and also to support the sashwhen it swings, a rest 33 is arranged in the window frame in the path ofthe upper sash, this rest being perforated, as shown at 34, to receivethe pin- -tle 35 of a plate 36 which is attached to the upper sash, nearthe bottom and one edge, as shown in Fig. 4. The pintle has projectingbarbs 37 near its lower end which, when in alignment with the slot 34,as is the case when the sash is in its normal position, can pass throughthe slot, but as soon as the sash is swung open, the barbs extend at anangle to the slot and below the rest, thus preventing the lifting of thesash. This arrangement forms the lower hinge of the upper sash, and toform the upper hinge the following constrnction is used.

On the upper part of the sash 11 and near one edge is a pintle 38,substantially like the pintle 35 described above, except that the barbs37 are omitted, and this pintle is adapted to engage a staple or eye 39on the parting strip 14, the eye or staple having its ends bentlaterally, as shown at 40, and countersunk in the frame so as to offerno obstruction to the free sliding of the sashes.

It will be seen from the above description that the sash 11 may beraised freely,in which case the pintles 38 and 35 slide from theirrespective supports. but when the sash is lowered, the pintles 38 and 35engage the eye 39 and slot 34 so that the sash may then be swung inward.The latch arm 23 of the upper sash 11 is adapted to lie, when opened, ina groove 4101? the frame, see Fig. 1, and in a recess 42 on the innerside of the parting strip section 14 Then the sashes are in theirnormalpositions, and the sections 14 and 15 are closed, the latch arms23 lie in the grooves or mortises 25, the window has essentially theappearance of an ordinary window, and the sashes may be raised orlowered in the usual manner.

When the lower sash is to be opened it is first raised, the button 31'turned beneath it, and the sash then pushed downward until it strikesthe button. This swings the arm 23 of the latch opposite the groove 29of the window frame. The section 15" of the bead 15 is then swung open,as shown in Fig. 1, the latch arm 23 turned inward so as to lie in thegroove 29, and the window sash may then be swung open while the latch 23is retained, as described, thus holding the sash cord in place; and whenthe sash is closed, the latch again engages it and may be turned back toposition, thus enabling the sash to be raised and lowered, as described.

If the upper sash is to be opened inward, the lower sash is firstopened, the upper-sash pulled down until it strikes the rest 33, thesection 14 of the parting strip is swung open, the latch arm 23 of theupper sash swung inward, as shown in Fig. 1, and the sash 11 may then beswung inward against the sash 12.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with the window frame and sashcords, of the vertically-movable and inwardly-swinging sash having itshinged edge directly secured to a sash cord, and a latch secured to theopposite sash cord and adapted to be swung into engagement with the freeedge of the sash or out of engagement with the same, substantially asdescribed.

2. The combination,with the window frame,

of swinging sections forming the lower ends of the inner bead andparting strip, the sliding sashes hinged at one edge and adapted toslide vertically, the hinged edges of the sashes being connecteddirectly to the sash cords, secured to the opposite sash cords andadapted to be swung into and outof engagement with the free edge of thesash, and means for retaining the latches in a fixed position when freedfrom the sashes, substantially as described.

3. The combination, with the window frame having a transverse groovetherein and the usual sash cords, of the swinging sash having one edgesecured directly to a sash cord, and a groove or mortise in its freeedge, a latch secured to the other cord and adapted to lie in themortise of the sash and swing into the groove of the frame, and a stopor button on the frame opposite the sash, substantially as described.

4. The combination, with the window frame and the vertically -slidingand inwardlyswinging sash, of eyes on the frame having openings on theirinner sides, and plates on the sash, the plates being slotted and curvedoutward and terminating in rods adapted to slide through and swing onthe eyes, the said rods being of greater diameter than the openings inthe eyes and the said openings of greater diameter than the thickness ofthe plates, substantially 'as described.

5. In a window, the combination with the frame and the inwardly-swingingand vertically-sliding upper sash, of a latch on the free edge of thesash adapted to be detached and held in the frame, a slotted rest in theframe in the path of the sash, an eye on the parting strip, and pintleson the sash adapted to engage the slot in the rest and the eye on theparting strip, substantially as described.

6. The combination, with the window frame and the sliding and swingingsash having a groove or mortise in its free edge, of the latch having atube to engage a sash cord, and a laterally-extending arm to lie in themortise of the sash, substantially as described.

7. The combination of the grooved or mortised sash, the latch havingatube to engage the sash cord and an arm to lie in the groove ormortise, and a spring catch on the arm to engage the sash, substantiallyas described.
